Ticket #6865 (closed defect: worksforme)
part of VM BIOS is overwritten during boot
|Reported by:||MarkCranness||Owned by:|
VirtualBox contains a 0x10000 (65536) byte BIOS used as the VM boots. At some point after VM boot, part of the BIOS (bytes F000:0F00 thru 0FFF) are overwritten and corrupted.
That range corresponds to part of function keyboard_init(), which apparently is not yet corrupted during POST, but at some later point is overwritten, and for the default BIOS this overwrite (apparently) causes no problems.
But if a user uses a custom BIOS file, this overwrite may cause problems.
